PICO Highlighting and Filtering: Frequently Asked Questions (FAQ) (Rayyan Beta)

How does PICO Highlighting work in Rayyan? 

• Rayyan highlights any PICO element that it detects with a 70% confidence level or higher
• Hovering over any highlighted text will show you what element of PICO it is related to and the confidence level.
• Comparison / Control is merged with Intervention, so for example you will see placebo as an intervention.
• You can turn on/off highlighting of PICO elements using the PICO Highlights button
• Unlike keyword highlighting of all instances of a word, PICO highlighting only occurs when the text is related to PICO.

How do PICO Facets (Beta) and PICO Filters work? 

• The 3 PICO facets (Population, Intervention/Comparison, Outcome) contain filters that rely on word truncation
• A PICO element with less than a 70% score will not be highlighted but will still be returned in the results of a filter
• The PICO filters order the results by the index with the most articles
• Like with all facets, combining filters within a facet produces "OR" and combining across facets produces "AND".
